A crusher is a heavy-duty machine used in mining and construction industries to reduce large rocks or ore into smaller pieces suitable for processing. The crushing process applies physical forces such as compression, impact, and shear to break the material.
Types of crushers include:

  • Jaw crushers: use two jaws (one fixed and one movable) to compress material. Ideal for primary coarse crushing.

  • Cone crushers: use a moving cone and a fixed outer shell to crush material by squeezing. Used for medium and fine crushing.

  • Impact crushers: use high-speed impact from blow bars to break material, suitable for softer or medium-hard materials.
    Advantages include high throughput, various product sizes, and durability. Disadvantages can be high energy consumption and maintenance needs.
    Used widely in mining, quarrying, road construction, recycling, concrete and asphalt production.

What is a mobile crusher, what is it used for, how does it work, and where is it used?
Mobile crushers are portable crushing machines mounted on wheels or tracks, allowing easy transportation and quick setup at different sites. The crushing principle is the same as stationary crushers but integrated into a mobile unit that includes feeders, crushers, screening, and conveyors.
Advantages: flexible use, quick adaptation to site changes, reduced transportation and setup costs, increased operational efficiency.
Disadvantages: generally lower capacity and energy efficiency compared to stationary crushers.
Used in excavation sites, short-term projects, construction sites, quarries, and recycling.

What is a stationary crusher, what is it used for, how does it work, and where is it used?
Stationary crushers are large, high-capacity crushing machines permanently installed at a fixed location. They process large amounts of material through multiple crushing stages, transferring material via conveyors to screening and further processing units.
Advantages: high throughput, durability, long service life, easier maintenance scheduling.
Disadvantages: high installation costs, limited flexibility, difficult to relocate.
Used in large mining operations, quarries, infrastructure and road projects, continuous production plants.

What are the differences between stationary and mobile crushers?
Stationary crushers are large, permanent installations with high capacity and require significant investment and space. They are not portable. Mobile crushers offer mobility, faster installation, and flexibility but generally have lower capacity.
Stationary crushers are suited for long-term, continuous operations; mobile crushers for temporary or changing sites.
They differ in energy consumption, maintenance, and operational costs.

What is a mobile crushing and screening plant, what is it used for, how does it work, and where is it used?
Mobile crushing and screening plants are integrated systems that crush and screen raw material on-site. They include feeders, crushers, screening units, conveyors, and control systems.
Material is fed into the feeder, crushed to appropriate sizes, screened to separate different size fractions, and conveyed to the desired locations.
Advantages: high mobility, fast setup, reduced transport costs, flexible production.
Used in construction sites, road building, mining, recycling, and energy sectors.
